Product Overview
The VSC8641 device is a low-power Gigabit Ethernet (GbE) transceiver ideal for Gigabit
LAN-on-Motherboard applications. The device’s compact, plastic low-profile quad flat
package (LQFP) or quad flat no-lead (QFN) package with an exposed pad is optimal for
footprint-sensitive applications.
Vitesse’s mixed signal and digital signal processing (DSP) architecture assures robust
performance. It supports both half-duplex and full-duplex 10BASE-T, 100BASE-TX, and
1000BASE-T communication speeds over Category 5 (Cat5) unshielded twisted pair
(UTP) cable at distances greater than 140 m, displaying excellent tolerance to NEXT,
FEXT, echo, and other types of ambient environment and system electronic noise.
The following illustration shows a high-level, generic view of a VSC8641 application.
